Comment 2 for bug 177783

I fond that this is actually a cairo issue. Cairo uses tmpfile to create temporary files for the PS backend. On MinGW the temporary file is on the root("\\") of the filesystem. This fails if the user does not has rights. There is also a discussion on the win list: http://www.nabble.com/temporary-files-in-wine-to8919379.html
I proposed to the cairo people a workaround for WIN32 systems: http://lists.cairographics.org/archives/cairo/2007-December/012529.html
